In a cocktail shaker, add fresh blackberries, lemon wedge, and mint simple syrup and muddle. Add in the whiskey and ice. Close shaker and shake vigorously. Strain cocktail into a glass with crushed ice. Top with seltzer, if desired. Add a few mint leaves and 3 blackberries to a skewer for garnish.

For the mint simple syrup:

In a small pot bring the water and sugar to a boil. Remove from heat and add the mint. Let sit until cool.

Tips: - Try your favorite kind of berrry such as strawberries or raspberries!- If you don't have time for simple syrup, muddle the mint leaves and some sugar.- Serve with Clinton's Roasted Tomato Dip!
